CC Andromedae (CC And) is a variable star in the constellation Andromeda. It is a pulsating star of the Delta Scuti type, with an apparent visual magnitude that varies between 9.19 and 9.46 with a periodicity of 3 hours.^[3]

The variability of CC Andromedae was discovered accidentally, by Olin Eggen on October 22, 1952, when he attempted to use it as a comparison star for measuring the brightness and colors of stars in the Andromeda Galaxy which is about one degree away from CC Andromedae.^[9]

The stellar classification of CC Andromedae is F3IV-V, as it shows intermediate characteristics between a subgiant and a main sequence star. The brightness variations are the result of 7 different pulsation modes, most of which are non-radial,^[7] making it a suspected Gamma Doradus variable too.^[10]
